**Table 8:** A comparison of the properties the hidden sources (h.s.) in four systems. Column 3 lists the total 15 $\mu$ m emission from the host galaxy in each case.

R1 = Ratio of 15 $\mu$ m (LW3) emission from the hidden
source in Mkn 297 to the hidden source in the other galaxy
(corrected for distance to Mkn 297).
R2 = Ratio of 15 $\mu$ m emission from each hidden source
to the total 15 $\mu$ m emission for its host galaxy.
